Example complaints

“While driving on highway, I slowed to turn off highway. After completing turn tried to accelerate but engine would not accelerate. Was able to move the car off roadway at idle RPM only. Car towed to local shop. A plastic piece on the end of the accelerator cable had disintegrated causing the accelerator cable to become disconnected from the engine throttle lever. This is the second time this failure has occurred. The plastic piece should have been made of metal. What if I had been in the middle lane of a six lane highway when this failure occurred?”
